IAIVA KYDCERa K5O-HC-C Series Miniature SMT Crystal Clock Oscillators

Category: Electronics, Kyocera America Inc, Oscillators

Overview

The datasheet presents the K5O-HC-C Series of Miniature Surface-Mount Technology (SMT) Crystal Clock Oscillators. These components are HCMOS compatible and are designed for frequencies ranging from 8 to 68 MHz. Equipped with a small SMT ceramic package, these oscillators are suitable for applications requiring miniaturization without compromising on performance.

Key Features

The oscillators boast several key features, including:

A frequency range of 8-68MHz.
Stability of ±100ppm and ±50ppm.
A maximum load capacity of 50pF.
Tristate output inhibit function for control flexibility.
Hermetically sealed packages to protect from environmental factors.
An option for bumped solder pads to assist in the washing process.

Ordering Information

To order, customers need to specify the type (K50-HC series), the desired stability range (±100ppm or ±50ppm), output compatibility (either CS-CMOS with a 45/55 duty cycle or CS-TTL with a 40/60 duty cycle), the frequency in MHz, the packaging type preferably R-tape and reel, and the option for solder pad bumps (‘J’ for no bump and ‘X’ for bumped).

Specifications

The datasheet elaborates on technical specifications relevant to TTL and CMOS classifications:

Operational temperature range is from -10 to +70 degrees Celsius.
Storage temperature ranges from -55 to +125 degrees Celsius.
Supply voltage is specified at 5 volts ±0.5V.
Supply currents are 40mA maximum for TTL and 50mA maximum for CMOS at 25 degrees Celsius with a 50MHz load.
Duty cycle is defined as 40/60 for TTL at 1.4 volts and 45/55 for CMOS at 50%V_DD.
The rise and fall times, load capacity, enable/disable times, and aging rates are detailed for precise design considerations.

Output Specifications

The oscillators’ logic levels for ‘0’ and ‘1’ states, as well as the input voltage thresholds for high and low are specified for TTL and CMOS, ensuring compatibility with different digital circuits.

Test Circuit and Output Waveform

Additionally, the datasheet includes diagrams of the test circuit and the expected output waveform, which aid designers in properly integrating the oscillators into their systems.
